PRODUCTION OF MECHANICAL/ELECTRICAL ENERGY FROM HEAT ENERGY WITH AND BY THE USE OF BUOYANCY FACTOR ON EVAPORATION OR SUBLIMATION AND CONDENSATION

There are various source of heat energy. Amongst the various sources Solar energy, waste heat form garbage, waste heat from transformers, waste heat from chemical reactions, waste heat from plant and machinery, heat from geo-thermal or the vast heat energy lying in the seas and oceans are some of the major ones which are free and unused. Apart from these, we can also produce heat energy from fuels like fossil fuels, hydrogen gas, forest products etc. A lot of heat energy is being wasted and though converted to mechanical or electric energy it is not that efficient. However, using the evaporation or sublimation and condensation process brought about through difference in temperature and the use of buoyancy factor to increase the efficiency of the energy production, the heat energy can be converted to mechanical or electrical energy in excess of hundred percent. Moreover, heat energy obtained from hydrolysis of some chemicals like salts or hydroxides and their dehydration for reuse or the ...

Production of Mechanical and/or Electrical Energy from Heat Energy By and With The Use of Buoyancy Factor on Evaporation or Sublimation and Condensation

Abstract There are various source of heat energy. Amongst the various sources Solar energy, waste heat form garbage, waste heat from transformers, waste heat from chemical reactions, waste heat from plant and machinery, heat from geo-thermal or the vast heat energy lying in the seas and oceans are some of the major ones which are free and unused. Apart from these, we can also produce heat energy from fuels like fossil fuels, hydrogen gas, forest products etc. A lot of heat energy is being wasted and though converted to mechanical or electric energy it is not that efficient. However, using the evaporation or sublimation and condensation process brought about through difference in temperature and the use of buoyancy factor to increase the efficiency of the energy production, the heat energy can be converted to mechanical or electrical energy in excess of hundred percent. Moreover, heat energy obtained from hydrolysis of some chemicals like salts or hydroxides and their dehydration for reuse ...

The buoyancy of the steam-filled chambers rotates the wheel, thus producing mechanical energy. Each chamber is filled with water when it arrives in its uppermost position. The resulting water flow rotates a partially immersed paddle wheel (29), thus producing further energy.

A gas separator for a submersible centrifugal pump or well has hardened cases on the components exposed to well fluid within the interior of the gas separator. The gas separator has a cylindrical sidewall with a bore. A shaft driven by a motor of the pump extends through the bore. An inducer is located in the bore for applying pressure to the fluid. In one type, a spinning guide vane imparts swirling motion for the well fluid to separate as it flows through a straight-through bore section. In another type, a tubular barrel locates in the sidewall, defining an intake chamber. The intake port in the sidewall is located above the intake port in the barrel, causing a reverse direction flow to separate gas from the liquid.
